Followed this official tutorial:\u00a0http:\/\/unity3d.com\/learn\/tutorials\/modules\/beginner\/physics\/assignments\/bouncing-ball<\/a><\/p>\n

My own version on GitHub<\/a>, and you can see it in action here<\/a> (watch for 10 seconds to see what happens with the balls in the way the interact).<\/p>\n

Steps to make this:<\/p>\n

    \n
  1. Create a new empty 3D<\/strong> project<\/li>\n
  2. Save the scene as Main.unity<\/strong><\/li>\n
  3. Hierarchy -> Create -> 3D object -> Plane<\/strong><\/li>\n
  4. Hierarchy -> Create -> 3D object ->\u00a0Sphere<\/strong>\n
      \n
    1. drag it up the y<\/strong> axis<\/li>\n<\/ol>\n<\/li>\n
    2. Hierarchy -> Create -> Light ->\u00a0Directional light<\/strong>\n
        \n
      1. drag it up the y<\/strong> axis above the sphere<\/li>\n
      2. set x rotation to 90<\/strong><\/li>\n<\/ol>\n<\/li>\n
      3. Click on the Sphere\n
          \n
        1. Add Component -> Physics -> Rigidbody<\/strong><\/li>\n
        2. Add Component -> Physics ->\u00a0Sphere collider<\/strong><\/li>\n<\/ol>\n<\/li>\n
        3. Assets -> Create -> Physics material<\/strong>\n
            \n
          1. Set Bounciness<\/strong> to 0.8 (to bounce forever set to 1<\/strong>)<\/li>\n
          2. Set Bounce combine<\/strong> to Maximum<\/li>\n
          3. drag it to the Material<\/strong> of the Sphere collider of the Sphere object<\/li>\n<\/ol>\n<\/li>\n
          4. Create a folder called Prefabs<\/strong> in the Assets<\/strong> folder\n
              \n
            1. Drag the Cube to this folder and delete it from the Hierarchy<\/li>\n
            2. Drag the prefab Cube from the Prefabs folder to the Hierarcy and you can now duplicate it with the same behavior<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
